Sounds like an amazing adventure, the central Sierra's have some great trails off highway 4. Slick rock, deer valley, etc. Great camping, fishing, and lakes in the area. Shaver lake area has some great trails all around. I think you've already done the Dusy-Ershim, but swap lake, brewer lake, etc are awesome too. Fordyce if you want to run a really tough trail near the Rubicon.
